[n4r9]

I'll explain what I mean about the semantics. Your original argument went thus:

> Per definition, if free will doesn't exist, then you can't say that "the illusion of the free will influences our lives more and in multiple ways."

By teasing apart your arguments, I now realise that you have bundled up the word "influence" into a package of meaning. You're presupposing "influence" to mean an agent consciously - and with free will - modifying their belief based on the environment. Same as what you mean by "shape our beliefs" just now. But I doubt OP was using the word "influence" that strongly; I think they were allowing for us to be machines without the free will necessary to "shape" their own beliefs. Therefore their point stands without the "endless loop".
